The pronunciation of the word "dance" gives rise to some confusion. In various regions both ways are encountered, and the criterion seems unclear. Aunt Macquarie simply states

Notice also the pronunciation of the vowel in "dance". Some speakers of Australian English use the same vowel as in "bad" for this word and others use the same vowel as in the word "hard".

The same seems to apply to some regions of the UK, in safe distance north of Oxford. ABBA consistently sing a decent Svedish mid-Atlantic ("dancing" rhyming with "man sing" or even "men sing" - approximately as I remember hearing it in Brisbane), but the Spookies may have found that too vulgar for Oxford, even in a parody.
